/* Phenome redesign, the App page (2026-09-29): the whole app, tab by tab, on
   3D phones (apple/phone3d.js) with the app's own screens (apple/app/harness*,
   rendered to assets/app-screens). Black chapters carry the phones: fans that
   turn in as they arrive, and pinned phones whose screen follows the text
   beside them (apple/app-page.js). White chapters carry the grids. Tiffany's
   privacy, questions and closing card follow, restyled by apple/type.css.

   The heading pair: a small line in the brand's navy over one 600 headline,
   the size the Ring, Band and testing pages use. */
